Abstract
The present invention provides a kind of piston push centrifuge welded type screen cloth：Welding engineering material is first processed into the grating 2 and reinforcement 3 of wedge section.Grating and reinforcement juxtaposition, the pad 1 of each juxtaposition is welded by welding equipment.After processing is in strip mesh sheet, then it is cylindrical wedge wire screen cylinder or sieve to roll into reinforcement.Grating increases screen slot quantity because extruding reduces grating width, therefore percent opening filtration efficiency is high；Grating Surface hardened layer is wear-resisting, improves screen cloth service life.Screen cloth is welded by automatic welding device, solder joint firmly, accurate size, filtering accuracy it is high, the up-narrow and down-wide cross-section structure in gap also avoids blocking.
Description
Technical field
The present invention relates to Centrifuge Techniques field, more particularly to piston push centrifuge screen device.
Background technology
Existing single two-level piston material pushing centrifugal machine screen cloth is made up of milling net and concatenation type bar net, and milling net is gradually substituted
The concatenation type bar net of finish and gap low precision, milling net manufacturing process is：Seamless pipe after lathe finishing internal-and external diameter again
Into the cylinder of appropriate length, some axial grooves of milling on cylinder is cylindrical will launch car with fluted cylinder, then backward-coiled
Arc sieve is made, then whole circle screen cloth is laid in rotary drum inner circle by some sieves.If patent publication No. CN101003045
A kind of milled screen stencil is disclosed, its manufacturing process is complicated, Xiyanping injection amount is big, cumbersome, milling grating across back of grinding the type that is made is big, mistake
Filter bar seam quantity is few so as to percent opening is low, and the acute angle that milling goes out is wear-resistant, screen cloth service life is short.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the present invention provides a kind of manufacture simplicity, and grating across back is small, bar seam quantity
It is many so as to percent opening is high, a kind of welded type screen cloth of long service life and install convenient.
The technical solution adopted in the present invention is：Above-mentioned piston push centrifuge welded type screen cloth is by grating and reinforcement
Constitute, it is characterized in that：Welding engineering material is first processed into the grating 2 and reinforcement 3 of wedge section.
Preferably, the grating and reinforcement juxtaposition, the pad 1 of each juxtaposition is welded by welding equipment.
Preferably, after processing and forming is in strip mesh sheet, then it is cylindrical wedge wire screen cylinder or sieve to roll into reinforcement.
Preferably, screen drum or some sieves are arranged on rotary drum inner circle, grating length direction and diameter parallel.
The beneficial effects of the invention are as follows：Grating because extrusion process so as to Surface hardened layer it is wear-resisting, have intensity very high, rigidity and
Bearing capacity, long service life.Increase screen slot quantity because extrusion process can reduce grating width, therefore percent opening is high, improves
Filter efficiency.Screen cloth is welded by automatic welding device, and solder joint is firm, gap size is accurate, screen slot is uniform, filtering accuracy is high,
The up-narrow and down-wide cross-section structure in gap also avoids blocking.The present invention can be applicable on single/double stage piston push centrifuge.
Brief description of the drawings
Fig. 1 is principle schematic diagram. of the invention.
In figure：1. pad, 2. grating, 3. reinforcement, 4. grating width, 5 screen slots.
Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples.
As shown in Figure 1：Piston push centrifuge welded type screen cloth is made up of grating 2 and reinforcement 3, welding engineering
Material is first processed into the grating 2 and reinforcement 3 of wedge section.
Grating 2 and the juxtaposition of reinforcement 3, the pad 1 of each juxtaposition is welded by welding equipment.
After the rectangular mesh sheet of processing and forming, then it is cylindrical wedge wire screen cylinder or sieve to roll into reinforcement.
Screen drum or some sieves are arranged on rotary drum inner circle, grating length direction and diameter parallel in the way of tensioner.
Above-described embodiment is the description of the invention, is not limitation of the invention, any to simple change of the invention
Structure afterwards is belonged to protection scope of the present invention.
Claims (4)
1. a kind of piston push centrifuge welded type screen cloth, its structure is：It is made up of grating and reinforcement, it is characterized in that：It is solderable
The engineering material for connecing first is processed into the grating 2 and reinforcement 3 of wedge section.
2. grating and reinforcement juxtaposition, the pad 1 of each juxtaposition is welded by welding equipment.
3. after processing and forming is in strip mesh sheet, then it is cylindrical wedge wire screen cylinder or sieve to roll into reinforcement.
